We've tried all the ones in that article you mentioned, and are currently
using classh - http://freshmeat.net/projects/classh - which is pretty nice,
in spite of being labelled alpha.

I've packaged it for c5 here:

  http://www.openfusion.com.au/mrepo/centos5-i386/RPMS.of/classh-0.092-1.of.el5.noarch.rpm

if you'd like to give it a whirl.
